So this is my first season vaulting. Right now I can clear 11' pretty comfortably and have the basics of my technique down. The problem is I am having a lot of problems with injuries. At my last meet, after taking my first warm up jump, all the way from the top part of my arm and shoulder, all the way through my shoulder bade. I kind of ignored it and just kept jumping but after I got home, I could barely move it. Extending my arm straight up, or if I put my arm in the position you would to flex your bicep and then try and move my arm back, it hurts like crazy. I have looked up shoulder pain and found of something called "shoulder shock". Does anyone have any idea what this is or any way to help me get better. Just another note, I have felt pain in my shoulder blade and shoulders for a couple of weeks but have just taken painkillers to cover it up, but it has reached a point where it is inhibiting basic movement.
